Thanks. I've tried this but am unclear how to specify a dependency on a class in the rt.jar. I've tried several "system dependency" syntax but unsuccessfully. Any thoughs on how to do this specifically? David

I am trying to deploy the geoserver.war. It is a standard war and I hopped that I could just "drop it in" to JBoss as7. Any thoughts? David

I'm working on a project with geotools, so I didn't tried anything with geoserver. Also I'm a newby with jboss and javaee, so I'm not really sure of what I'm saying....

The problem that is causing this messages is that geotools is looking for resources in the META-INF folder inside the jars of the many geotools modules, byut these resources are not made available to the jars by the classloader.

Now I got a different error (java.lang.ClassNotFoundException: org.geotools.factory.FactoryRegistry from [Module "org.geotools:main" from local module loader @175093f1 (roots: /Users/imac/Library/jboss-as-7.1.0.CR1b/modules)]), but I'm quite sure this error is related to the point 1) (I didn't include all the jars in "my" geotools module)

I hope this is helpful, becouse in the next days I need to deploy a geoserver instance....

Once I solved the first error (ClassNotFoundException com.sun.imageio.spi.FileImageInputStreamSpi), I was able to configure layers and view maps. I wonder if these are more warnings and later resolved after the full JAR is loaded. Is you geoserver unusable after fixing just the FileImageInputStreamSpi error?

I was not working with geoserver, but with a different application that uses the same library as geoserver (geotools). Actually, as you noticed before, everything works without my solution , but I didn't try to use the reprojections utilities (it seems that the warnings are referring to math transformations, which are involved in coordinates reprojections). Have you tried with geoserver to perform some geographic reprojections?

Sorry, Jaikiran, that isn't documentation. That's an example. Documentation would include descriptions in complete sentences, some variations to establish the pattern and more than one example.

From that entire chapter on classloading which explains various different things including some examples, you find a misconstructed sentence in a xml comment and instead of asking someone to fix that sentence or explain it, you just belittle the entire documentation. Nice!
